Traffic congestion causes more problems than just being stuck in traffic. There are real effects on the health, quality of life and wallets of taxpayers.
Lakes are the final resting place for many of the Earth's plants – and these organic graveyards are about to get a whole lot busier.
Developers pay more tax to refurbish than demolish and rebuild – but there's a very easy fix.
Nitrogen-fixing bacteria help tropical phytoplankton absorb carbon dioxide, creating a biological pump in the oceans.
Sulfur contaminates gasoline and coal, and when these fuels are burned, sulfur dioxide is emitted, causing pollution and respiratory issues. Now there may be a new, cheaper way to remove it.
Scientists from all over the world agree that the impacts of climate change will get worse, unless action is taken now.
Carbon dioxide makes up less than one-twentieth of 1% of Earth's atmosphere. How does this relatively scarce gas control Earth's thermostat?
The United Nations is calling on world governments to step up action against climate change. Can China, the world's biggest carbon emitter, fulfill its pledges?
The Amazon will take a lifetime to recover from this year's fires – if it ever does.
What exactly is inside those red fire extinguisher canisters, and does it work better than water?
Scientists introduced credible climate change to the world in 1979, but it's taken decades for their message to sink in.
Could our best shot at stopping climate catastrophe be restoring forests on a massive scale?
A key tool for capturing and storing carbon may have been hiding in plain sight all along.
Carbon offsetting is one way of doing it – but sometimes the simplest methods work best.
Carbon dioxide levels in the atmosphere are at 414 parts per million. But thanks to a recalculation of methane's warming power, the total amount of greenhouse gases is now equivalent to more than 500.
A scientist explains how global warming is affecting the entire world – from the mountains, to the sea.
Electricity consumption will grow as more people switch to electric cars – but this could drive up emissions, unless power is sourced from renewables.
Don't let stock markets reports convince you that when the markets are up, all is well in the world. When the market is up, carbon dioxide in the atmosphere is up, and the global environment is down.
Thousands of years ago, carbon gases trapped on the seafloor escaped, causing drastic warming that helped end the last ice age. A scientist says climate change could cause this process to repeat.
Phytoplankton are tiny, but they do important work.
